Magnetization of Narrow GaP Semimagnetic Semiconductor Hg_(1-x)Mn_x Te
窄禁带半磁半导体Hg_(1-x)Mn_xTe的磁化强度

The magnetization measurements of Hg_(1-x)Mn_xTe for samples with x=0.06,0.08, 0.12,0.16 in the temperature range 1.5K to 30K and magnetic fields up to 7T have been carried outby using the extraction method.Based on the mean field theory,a modified Brillouin func-tion is fitted with the data very well over the entire range.The inverse susceptibility is showna Curie-Weiss behavior even at high field with a paramagnetic Curie temperature and indica-tes that there is an antiferromagnetic exchange coupling among Mn ions.
